Technical Drawing Standards: Line colours.

Should you use colour line work on your drawings?

The British standards for technical drawing suggest that you don’t use coloured lines on your drawings. This makes sense from a Setting out point of view, most of our drawings will be photocopied at some point in their life and the coloured lines won’t show up.

The British standards do make a provision if you want to use coloured lines in your drawing, you just need to add a note or key to explain what the coloured lines mean.
